Pass env:foo also to pre/post scripts

Discussed in #240

I couldn't find my answer in the docs.

Are env:.... variables passed to the pre/post scripts also? I'm interested in having one place for the vars and using them both in pre: and also running the app.

Turns out this was partially implemented in #189, back in February, also for v4.3 ... so I'll just rip out the SERVICE_ENV_FILE* stuff and replace it with the variables sourced instead. Basically:

sh -ac '. /path/to/env; exec ./pre-post.sh'

This means the env file can be a simple foo=bar file, which Finit can read and call setenv() on all variables, and the user do not need to call export on all variables -- additionally, any functions defined in an env file could be used by the pre-post scripts, but would go ignored by Finit.

Nice! That should make things very flexible.
